I'm making a big level, and I need random numbers like: 1/3 of the time, X happens. or 3/7 of the time, Y happens, 1/7 of the time Z happens, and the remaining 3/7 of the time, W happens. I will be needing a lot of them, so something that can be reproduced in mass would be apreciated.-----------------puzzled

Eh? I don't understand.I understand how to trigger it, but i can't figure out how to get it to trigger something else, right now, i basiclly learned nothing.Not to be rude, or anything, the dude, but I just don't understand.Example: In my level there is an area where you have to search the grass for a trapdoor.I want 1/5 (one-fifth) of the time the trapdoor is found. the other 4/5 of it, nothing.Right now, with what i know, i have a button labled "search grass", and thats it.demonstrations would be apreciated most, where i could load it in the editor and figure it out.-----------------puzzled

Haha, being a teacher is difficult sometimes.I'll explain TheDude's method in more detail.

The first step is to use the random integer function.In your case, because you have probabilities with the common denominator 7, you want 7 possible results for the random integer.The easiest way is just to take the numbers from 0 to 6. You would have this in your code as:

local[x:"NAME"] = FastIntegerRandomBetween (0, 7)

The reason why the limits are from 0 to 7 is because the upper limit is exclusive (does not include the 7 itself).So, the variable will be assigned either 0, 1, 2, ... 5, or 6.

Now you need to do a few comparisons.Because you have a 3/7 chance that Y happens, then it makes sense if Y happens if the random variable is 0, 1, or 2.So make Y happen if the variable is less then 3.

There's only a 1/7 chance that Z happens, so it can be assigned just one number. It makes sense if it is simply 3.Thus, make Z happen if the variable is equal to 3.

Then there's another 3/7 chance that W happens, so we can just let it be any of the remaining numbers: 4, 5, or 6.So, make W happen if the variable is greater than 3.Otherwise, you could have W execute in an else statement.

I actually made two custom functions based on probabilities for fun (written in v1.60):

One of them is a very simple boolean assign function (the code is very easy to read, as it's only three lines).The other one is a bit more complicated, and is a string assign function.

The string assign function has two inputs, both of which are expressed like ratios (with colon separators).The first input is the list of output results, which describes the possible string outcomes for the function.For example, if your possible results are Y, Z, and W, then you'd list the results as Y:Z:W.The second input is the list of probabilities, expressed purely as a ratio (you can use noninteger values).For example, taking the probabilities above, you'd input 3:1:3 into the second part.

I personally recommend that you avoid using my custom function, as it is almost always more efficient to describe the probabilities out like above.But you can still use it however you like, as it can handle any number of possible results.-----------------Hopefully PA is inconsistent.
